Comprised of hundreds of components per pair of cables, the TriFocal-XL is formatted in a seven layer, poly-concentric geometry. This is one of the most sophisticated loudspeaker cables ever designed. Termination alone takes a full eight hours to complete a single matched pair. A production run of 250 feet (76 meters) of this cable takes over 50 hours of machine time. TriFocal-XL will allow the most intimate union possible between triwired loudspeakers and an amplifier.
